So that's a couple of people now who've reported Navy ships firing upon UFOs. And the news is being hidden. Generally the military and news outlets will report such things if they involve russian or chinese aircraft. I don't know the law but I think they're supposed to let population know.
Since the UFOs are not reported to be attacking, it's all hanging on a thread. But if you're the USG and you have a report of one your ships firing at a big black triangle hovering over it, who do you turn to? Who is the authority? There is none afaik.
